Wondercave...

Went to the Wondercave the other day in the Cradle of Humankind
A 1.5 million year old cave that was mined by the italians in the late 1800's for lime
40 meters deep into the ground and a consistent 16'C year round
Very damp inside
And dark
Had to walk down 87 stairs to get to the lift and up 127 to get back to top
